tools/power turbostat: use wide columns to display large numbers

Browse Source 
When a counter overlfows 7 columns, it shifts the remaining
columns to the right, so they no longer line up under
their column header.

Update turbostat to dectect when it is handling large
numbers, and switch to wider columns where, necessary.
